According to the most recent EIA figures on their "This Week in Petroleum" web page, the demand for gasoline on 9/23 ROSE over 9/16 and it returning to the year ago value.

So, this seems to indicate, if any government report is reliable these days, that demand has not slowed despite a slight the increase in the week over week price of gasoline.

It is hard for me to imagine that society as a whole in this country is smart enought to rapidly change their lifestyle considering all the happy talk that they see and hear from their leaders.  As long as banks still extend credit, gas will be purchased regardless of price.  The papers were full of stories about the huricanes doing less damage than thought and stories like Bush urging conservation are buried.  Has anyone seen any increase in ads for public transportation or anything to start conditioning the populace to conserve?

I would guess that as gas prices fell post Katrina and per Rita demand rose. Also Right after Katrina there was more panic buying of gas which caused a rapid spike in price and spot shortages. Now (rightly or wrongly) there is not such a panic and the Rita Spike has played out over a week or so rather than a couple days.

One thing I have noticed is this time Gas and Diesel prices have moved up together with Diesel climbing back above Gas(here in Indiana). Last time Gas was 3.29 and diesel was 2.89, this time it's 2.94 and 3.05 respectively. Also saw where the IRS is allowing OTR trucks to use Off Highway diesel (which is not subject to excise tax). I wonder how much of a hit there will be on taxes.
